摘　　要：为改善PA6（尼龙6）超细纤维／聚氨酯复合材料染料上染率低和配伍性差的问题，采用控制染料先渗透后结合的染色方法，优化的染色工艺条件为：乙酸0．8％～1％、染料2％～3％（omf）、浴比1：15。在较佳工艺条件下染色时，染料上染率可达99．5％，基布K／S值能满足合成革基布的要求；该染色方法无需考虑染料半染时间，对染料的配伍性要求较低；染色后的复合材料热稳定性及力学性能变化不大。Aiming at the problems of low dye-uptake and poor dye compatibility, the dyeing of PA6 micro fiber/PU composite materials are achieved by penetrating process and binding process orderly. The optimal dyeing process is defined as follows： acetic acid 0.8%-1%, dyes 2%~3%（omf）, liquor ratio 1 ： 15. In this process, the dye-uptake reaches 99.5% and the K/S value can meet the requirements for synthetic leather matrix. There is no need to consider half-dyeing time and it＇s less demanding on dye compatibility. After dyeing, the thermal stability and mechanical property of the composite change little.
